Bicycling Magazine published The 30 Hardest Hill Climbs in the World (most recently updated in 2022). I have always been more enthusiastic than talented but let me look at their list. Some I have done. Some I will never do (logistics mostly). And some I would like to do or do again.
The list:
- Mount Evans, Colorado
- Mount Lemmon, Arizona
- Onion Valley, California
- Whiteface Mountain, New York
- Mount Mitchell, North Carolina
- Mount Washington, New Hampshire
- Le Mauna Kea, Hawaii
- Passo Del Mortirolo, Italy
- Mont Ventoux, France
- Rila, Bulgaria
- Passo dello Stelvio, Italy
- Passo Gavia, Italy
- Alto de Letras, Columbia
- Alto de l’Angliru, Spain
- Col du Galibier, France
- Mount Baldy, California
- Haleakala, Hawaii
- Col du Tourmalet, France
- Alto de la Lenia, Columbia
- Hardknott Pass, United Kingdom
- Alpe d’Huez, France
- Powder Mountain, Utah
- Pico el Aguila, Venezuela
- Wuling Mountain, Taiwan
- Tong La Pass, Tibet
- Grimsel Pass, Switzerland
- EL Teide, Canary Islands
- Monte Zoncolan, Italy
- Grossglockner, Austria
- Muro di Sormano, Italy
The ones I have climbed are in bold. I came close to climbing the Mortirolo (#8) in 2014. I was on a Trek Travel trip in Italy and we were supposed to ride Mortirolo but we were rained out (they couldn’t get the support vans up there) and I never felt the need to get back there.
There are two on this list I may still do, Whiteface (4) in New York and Grimsel Pass (26) in Switzerland. I’d give myself about a 49% chance of climbing Whiteface and a 15% chance of Grimsel Pass.
Note: Since updating this to suggest that there was slightly less than a 50/50 chance of climbing Whiteface I realized I was confusing my mountains. I was thinking about Ascutney in southern Vermont, just off I-91. I may get to Ascutney, but I don’t think I will get to Whiteface.
Also, note to self: There is a nice primer on Swiss climbs if you’re serious about Grimsel Pass. And another at Cycling Challenge on the Gotthard Challenge and I will prioritize the Gotthard Challenge over Grimsel Pass.
I’ll keep climbing as long as I am able.
And now the new stuff. I introduce PDI – PJAMM Difficulty Index There is no perfect way to evaluate the difficulty of a climb, and indeed, it can be personal. A lightweight climber (not me) may find a longer steady climb more difficult than a shorter steeper climb. Likewise, a heavier rider may do better on long climbs but go into difficulty when the road turns steep. The PDI is an attempt to compare climbs. Your experience (and mine) may differ.
This looks at climbs I have done and is not a comparison of how difficult they are. The most difficult one listed here is Mount Washington, NH, and, IMHO, it’s not even close. Keep that in mind when looking at PDI.
And now the climbs, of the “Top 30,” I have done.
Mount Evans, Colorado
I first climbed Mount Evans in 2007 on a straight bar rental road bike. Then again in 2016 on my own bike – and I saw a bear! It was easier on my own bike after 400 miles and one week of riding in the Rockies. When I rode it in 2007 I said, “Never again.” And then rode it in 2016. I never learn. It is one of two climbs that I said, “Never again.”
Note: Mount Evans was renamed Mount Blue Sky in 2023.
Mount Lemmon, Arizona
This climb is absolutely beautiful. Just make sure you carry enough water. It is extremely dry and there are no water supplies until near the top. Camelbaks work. The locals know to start at 6:00 a.m. because it will bake. I climbed it in October 2011.
Mount Mitchell, North Carolina
Mount Mitchell is the highest point east of the Mississippi. It was never a bucket list climb for me but I climbed it in November 2020. Real cyclists can punish themselves by riding 100 miles from Spartanburg, South Carolina in the Assault on Mt. Mitchell.
Mount Washington, New Hampshire
Mount Washington, New Hampshire. The hardest of them all. I have ridden it nine times; the first time without changing my gearing. Two other times I was there the race was canceled (weather – of course).
The years: 2007*, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2021, 2022, 2023* (2007 and 2023 were canceled).
Mont Ventoux, France
If I only had a Whoop Band in 2011. I had driven about six hours, was locked out of my pre-paid chateau, and spent the night sleeping in my rental car. And then I climbed Mont Ventoux. It became rainy and very windy but I had one chance in my life to get to the summit so I did.
Passo dello Stelvio
Her 48 switchbacks are calling me back. I first rode it in 2014 and planned a side trip while in Switzerland in 2017 but warm turned to cold and sun turned to rain and snow on the beautiful pass. I probably will never get back but would love to ride this one again.
Gavia Pass
A cold, wet day in June, 2014, my iconic image is seeing a bunch a teenage boys pushing their bikes up the climb where we rode. This was the snow-covered pass made famous by Andy Hampsten when he rode into Giro d’Italia and cycling history in 1988 (although he did not win that day – Erik Breukink did).
Col du Galibier
July 19, 2011, was the coldest I have ever been on a bike. I rode to the summit of the Col du Lautaret as rain turned to snow and had to abandon my attempt to climb the Col du Galibier. I never thought I would get a second chance. But in 2024 I went to France with Cykelnerven and was able to climb the Col du Galibier.
Mount Baldy, California
One of Southern California’s toughest climbs, this seemed to be a staple in the Amgen Tour of California. It was never a bucket list climb for me but when I went to Phil Gaimon’s Cookie Gran Fondo in 2018 I made it a point to find this climb.
Col du Tourmalet
In 2011 I went up and over the summit and back up again to watch the Tour de France. In 2010 I climbed it from both sides but was stopped 4km from the summit by the police for the Tour de France. It’s tough.
I climbed this in its entirety but not all at the same time. In 2010 while on a Trek Travel trip, we started in Lourdes and rode this climb to within four kilometers of the summit. About six km down we had a tent for our viewing location but a number of us rode to the 4 km spot where the road was blocked off to the summit.
In 2011 I returned to France and rode up the Tourmalet from the Campon side. Riding with my friend, Adrian, we went over the top and started to descend this side of the mountain. My rear wheel had a wobble. When we reached the tent area of the last year we turned around and went back up the Tourmalet to make our viewing location at the summit.
In terms of miles, I climbed nine miles of this climb in 2010 and, by accident, rode the final 2.5 miles in 2011. It’s a bit longer on this side (11.5 v. 10.5 miles) and a little less steep (7.1% vs. 7.6%). I struggled from the other side on 2011 and would say this side is a bit easier despite the PJAMM score of 28.6 vs. 28.4.
Alpe d’Huez
Another iconic climb. Probably the second one I would most like to repeat (after Stelvio).
And that is it. It’s a nice list of 30 climbs. According to the PDI (PJamm Difficulty Index, the three most difficult are Mt. Washington (NH), Mount Evans (CO), and Stelvio Pass. Personally, Mount Washington is much harder than Mount Evans or Stelvio Pass. For my type of riding the steepness of Mount Washington is a killer. It’s the only climb that I have to change the gearing of my bike.
I would put Mount Evans second because it along with Mount Washington are the only two climbs that I said, “Never again” immediately when I finished.
I will add one more.
Gotthard Pass, Switzerland
I would submit that the PDI completely misses on this climb in Switzerland. Granted, of the climbs in the list that I have done, the difficulty level of the Gotthard Pass is the easiest. I include it for the scenery, the switchbacks, and the surface. It’s almost eight miles of cobblestones. The difficulty level of riding on cobblestones increases greatly because of this road surface. It definitely belongs.
